It is desirable that the remote controller ( 401 ) and the drone ( 100 ) perform wireless communication by Wi-Fi or the like.
- a farm field ( 403 ) is a rice field, an upland field, or the like targeted for chemical spraying by the drone ( 100 ).
- the topography of the farm field ( 403 ) is complicated, and there is a case where the topographic map cannot be obtained in advance, or the topographic map and the situation of the site are inconsistent.
- the farm field ( 403 ) is adjacent to a house, a hospital, a school, a farm field for other crops, a road, a railroad, and the like. Further, there may also be obstacles such as buildings and electric wires in the farm field ( 403 ).
- a base station ( 404 ) is a device which provides a master unit function of Wi-Fi communication and the like. Desirably, the base station also functions as an RTK-GPS base station to provide the accurate position of the drone ( 100 ) (the master unit function of Wi-Fi communication and the RTK-GPS base station may be independent devices).
- a farm cloud ( 405 ) is typically a group of computers operated on a cloud service and related software, and it is desirable that the farm cloud ( 405 ) is wirelessly connected to the remote controller ( 401 ) via a mobile phone line or the like.
- the farm cloud ( 405 ) may analyze the image of the farm field ( 403 ) photographed by the drone ( 100 ), grasp the growth status of crops, and perform processing for determining a flight route. Further, the drone ( 100 ) may be provided with the stored topographical information or the like of the farm field ( 403 ). In addition, the history of the flight of the drone ( 100 ) and photographed images may be accumulated to perform various analysis processes.
- the drone ( 100 ) takes off from a landing point ( 406 ) outside the farm field ( 403 ), and returns to the landing point ( 406 ) after spraying chemicals on the farm field ( 403 ), or when it becomes necessary to replenish the chemicals or charge.
- a flight route (entry route) from the landing point ( 406 ) to the target farm field ( 403 ) may be stored in advance in the farm cloud ( 405 ) or the like, or may be inputted by the user ( 402 ) before starting take-off.
- FIG. 5 is a schematic diagram illustrating a control function of the embodiment of the chemical spraying drone according to the present invention.
- a flight controller ( 501 ) is a component which controls the entire drone, and specifically may be an embedded computer including a CPU, memory, related software, and the like.
- the flight controller ( 501 ) controls the flight of the drone ( 100 ) by controlling the rotation speed of the motors ( 102 - 1 a , 102 - 1 b , 102 - 2 a , 102 - 2 b , 102 - 3 a , 102 - 3 b , 104 - a , and 104 - b ) with control means such as electronic speed control (ESC) on the basis of the input information received from the remote controller ( 401 ) and the input information obtained from various sensors described later.
- control means such as electronic speed control (ESC)
- the actual rotation speed of the motors ( 102 - 1 a , 102 - 1 b , 102 - 2 a , 102 - 2 b , 102 - 3 a , 102 - 3 b , 104 - a , and 104 - b ) is fed back to the flight controller ( 501 ) to monitor whether or not a normal rotation is performed.
- the rotor blade ( 101 ) may be provided with an optical sensor or the like so that the rotation of the rotor blade ( 101 ) is fed back to the flight controller ( 501 ).
- the software used by the flight controller ( 501 ) is preferably rewritable through a storage medium or the like for function expansion/change, problem correction, or the like, or through communication means such as Wi-Fi communication or USB.
- a part of a calculation process used in the control by the flight controller ( 501 ) may be executed by another computer existing on the remote controller ( 401 ), the farm cloud ( 405 ), or another place. Since the flight controller ( 501 ) is highly important, some or all of the components thereof may be duplexed.
- a battery ( 502 ) is a unit which supplies power to the flight controller ( 501 ) and other components of the drone, and is desirably rechargeable.

- a warning light ( 521 ) is a display unit such as a strobe light for notifying the drone state (particularly an error state). These input/output units may be selected according to the cost target and performance requirements of the drone and may be duplexed or multiplexed.
- the drone according to the present invention is premised on an operation by non-specialists. In this case, it is important to provide a safety mechanism, or “a foolproof mechanism”, that prevents operations leading to dangerous situations although humans make mistakes on operations of a machinery, or the machinery has an abnormality or a failure. Therefore, the drone according to the present invention provide an interlock control as describes below.
- the drone ( 100 ) is desirable to spray chemicals or the like based on a farm field topography data prepared in advance.
- the farm field topography data is preferably described in a geographic coordinate system used by GPS.
- the farm field topography data is preferably consolidated on the farm cloud, downloaded at take-off the drone ( 100 ), and stored in a memory of the flight controller ( 501 ).
- the farm field topography data may be managed locally on the memory of the flight controller ( 501 ) by using a storage medium, such as an USB memory.

Flying the drone ( 100 ) without knowing what is on the way to the target farm field increases a risk of accidents. When such a situation occurs, an error message is preferably displayed on the remote controller ( 401 ) to encourage the drone ( 100 ) to move into an area of the farm field topography data. Further, in this case, the flight controller ( 501 ) may allow a mode without flight (for example, a maintenance work or a replenishment of chemicals).
- the flight controller ( 501 ) of the drone ( 100 ) according to the present invention preferably prohibits take-off (does not transmit rotation command to the motor ( 102 )) when it becomes clear from the stored farm field topography data that an area (a traffic or a pathway), where people and cars may pass, is on the intrusion pathway during takeoff.
- the flight controller ( 501 ) of the drone ( 100 ) according to the present invention preferably prohibits take-off (does not transmit rotation command to the motor ( 102 )) when it becomes clear from the stored farm field topography data that obstacles, such as utility poles, overhead wires, trees, or the like, are on the intrusion pathway.

For example, an accident is assumed that a drone for spraying herbicide is brought to the farm field where spraying pesticide is needed. When such a situation occurs, the error message is preferably displayed on the remote controller ( 401 ) to inform the situation to the user ( 402 ). In this case, the flight controller ( 501 ) may allow the mode without flight (for example, the maintenance work or the replenishment of chemicals).
- the flight controller ( 501 ) of the drone determines that a wrong farm field is specified based on a direction of the airframe measured by a magnetic sensor ( 506 ), the position of the airframe measured by the GPS ( 504 ), and the intrusion pathway information, and preferably prohibits take-off (does not transmit rotation command to the motor ( 102 )).
- the error message may be displayed on the remote controller ( 401 ) to confirm the user ( 402 ) for take-off.
- the drone ( 100 ) preferably performs regular maintenance and inspection work with the manufacture's regulations and various safety standards.

- the information may be stored in the farm cloud ( 405 ).
- the flight controller ( 501 ) of the drone ( 100 ) read the history of the maintenance work at take-off and prohibits take-off (does not transmit rotation command to the motor ( 102 )) when a predetermined standards are not met. For example, the predetermined standards are not met if more than a specified time passes from a last maintenance, or if the drone ( 100 ) is operated or flown more than a specified time from the last maintenance.
- the battery ( 502 ) is an extremely important component in the operation of the drone, and is a component highly like to cause an accident or a failure.
- Lithium-ion batteries the mainstream technology for large-capacity batteries at present, are known to increase a risk of ignition and explosion due to a thermal runaway when they are in a high temperature state.
